ABSTRACT:
A motor vehicle is controlled to run at a constant speed by calculating a target engine rotational speed based on a preset vehicle speed and a gear position of a transmission, determining an upper limit for the amount of fuel to be supplied to maintain the target engine rotational speed, and controlling the amount of fuel to be supplied below an upper limit based on the difference between the preset vehicle speed and the speed at which the vehicle is running.
